GRADE COMPUTER

Check the appropriate button and enter all the fields up to at least Exam 1.  Exam scores are to be entered on a 0-100 scale:
 
Attendance bonus points YesNo
Your homework total /
total possible points
 /
Your minimum homework /
no. of homeworks
 /
Exam 1 score %
Exam 2 score %
Exam 3 score %
Final exam score %
Course average: %


For better than overall course average you need at least this grade on the next exam
90 average %
80 average %
70 average %
60 average %

This grade computer is for information purposes only. My records and computation are what will determine your final grade.  Let me know if the computer acts in a suspicious way.

How to use: the grade computer will give your current course average as well as tell you what you need to get on the next exam in order to have a target course average.  You may also play with entering as many hypothetical grades as you wish to see what effect they will have on the final grade.

You will need to provide all the fields up to at least exam 1 in order for the computer to work.  Homework maximum and the number of homeworks has been filled-in and will be updated periodically.  If the information is out of date, you may enter the newest data.  Keep in mind that exam grades are entered on a 0-100 scale. 

Example: after 4 homeworks you have homework scores of 24/26, 31/34, 23/28, 17/18 and you had two exam scores of 37/50 and 45/60.  Enter in the first four rows:

95 and 106 (24+31+23+17 and 26+34+28+18)
17 and 4
74 ( = 37/50 * 100)
75 ( = 45/60 * 100)

"Course average" will tell you what grade you have based only on the elements earned so far.  The fields under it give you the grade (on a 0-100 scale) you need on exam 3 in order to have a desired course average once exam 3 is included in the computation.  If any of those numbers is higher than 100, the desired course average cannot be achieved.  If you, for example, now enter the number from "80 average" into the (empty) exam 3 field and click "compute" again, the course average will be about 80% (allow for inexactness here because of rounding).  You may enter hypothetical grades for exams 3 and the final exam to explore what happens to the final grade.

Note 1: the computer assumes that homework is always 15% of the grade.  To handle dropping the lowest homework grade in a situation where homeworks do not have equal number of points, the homework percentage is computed as follows:

(your hw total - your hw min) / (max hw total - average hw max)

Note 2: the computer ignores any information after the first blank exam field (try it: if you enter just exams 1 and 3 you will see that nothing changes after you alter exam 3).
